FRANK E. V. CHAPMAN, OF ASBURY PARK, NEW JERSEY, ASSIGNOR OF ONE-FOURTH TO FRANK DURAND, CHARLES H. IVINS, AND JAMES D. CARTON, PARTNERS AS DURAND, IVINS & CARTON, OF ASBURY PARK, NEW JERSEY.

WHEEL-MOUNT.

T 0 all whom it may concern:

Be it known that I, FRANK E. V. CHAP- MAN, citizen of the United States, residing at Asbury Park, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in lVheeL Mounts, of which the following is a specification.

This invention relates to trolley for carrier systems operating by means of an overhead lead or conductor, the purpose being simplicity and durability of construction, and the provision of a trolley which will run easy and without noise and not require frequent repairs.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the top portion of a car showing the trolley head in operative position; Fig. 2 is a vertical section of the upper portion of the trolley head, the shanks of the fork members being in full and the clamp sleeve being partly in section; Fig. 8 is a section on the line XX of Fig. 2; Fig. 4 is a perspective view of a fork member, the lower portion of the shank being broken away; Fig. 5 is a detail section of a pivot clamp nut.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to Fig. 1 of the drawings, the lead or over-head line or conductor is indicated at 1, the top of the car at 2 and the trolley pole or arm at 3. A sleeve 4 is fitted to the upper end of the pole or arm 3 and is split for a short distance from its upper end and is provided with an outer flange 5 a short distance from its upper extremity, the portion beyond the flange being externally threaded to receive a clamp nut 6 by means of which the upper portion of the sleeve is contracted and caused to firmly Specification of Letters Patent.

Serial No. 762,885.

clamp the shanks 7 of the fork sides or members 8 comprising the head proper of the trolley.

The fork sides are similarly formed, being rights and lefts and their upper ends are widened and form disks 9 which have their outer portions beveled in opposite directions, as indicated most clearly in Figs. 2 and 3, and as a result of this construction the opposing sides of the disks 9 flare outwardly, thereby serving to guide the trolley when fitting it to the lead or conductor 1. Each of the disks 9 is formed with a central opening 10 to receive the ournal 11 of the trolley wheel 12. The inner face or side of each of the disks 9 is centrally depressed, as shown at 13, to receive the adjacent end portion of the trolley wheel which fits snugly therein. A boss, gland or tubular extension 11 is formed with or applied to each of the disks 9 and projects outwardly therefrom in line with the opening 10 and is externally threaded to receive the combined pivot and clamp nut 15, which is adapted to be secured thereon. The shanks 7 of the fork sides come together and are fitted in the sleeve 4 and are secured therein at the required position by means of the clamp nut 6 in the manner aforesaid.

The trolley wheel 12 is anticlastic in shape and its end portions fit snugly within the circular recesses 13 formed in the inner faces of the upper portions of the fork sides, and this trolley wheel is provided with end journals 11 which obtain bearings in the openings 10 and which have their outer ends depressed to receive the convex ends of the pivot pins or studs 16 formed with or ap plied to the parts 15. The trolley wheel and journals are preferably formed of a single piece, thereby obviating the formation of joints, but it is to be understood that the parts may be separately constructed and fitted together in any substantial manner.

The member 12 may be constructed of copper or any other metal which may be found efficient under the particular conditions for which each trolley wheel is to be used. The only requisite of the metal employed in constructing the member 12 is that it shall be material which is equally as soft, if not softer, than the trolley wire.

The nuts 15 have their outer portions chambered, as shown at 17, to receive and contain a lubricant by means of which the journals are kept oiled and cool, and these chambers 17 surround the pivot pins or studs 16, which are in co-aXial alinement with the journals 11 and the threaded openings 18 of the nuts. Lubricant of any kind may be supplied to the chambers 17 in any conve ient way. Spring steel washers 19 are interposed between the fork sides and the nuts 15 and are slipped upon the bush ing or threaded offstanding tubular extensions 14:. The fork sides are constructed so as to fittclose against the ends of the trolley wheel 12. Endwise play of the trolley wheel is prevented and wear compensated for by. turning up the nuts 15 which causes the parts 16 to bear against the ends of the journals 11, as will be readily understood.

The disks 9 are connected by a rod 20, the terminals of which are reduced, the shoulders 26 formed by reducing the terminals being out obliquely to conform to the inner face of the disks 9. The terminal 23 is threaded into one of the disks 9, being placed in the disk as the disks are assembled, the other terminal 24 extending through the other disk 9 and receiving a nut lock 25. The rod 20 thus prevents the disks from separating when the pole leaves the trolley wire. The trolley wheel 12 may be constructed of any suitable material, but it is preferably formed of an alloy which provides a suitable electrical conductor.

Having thus described the invention, what is claimed as new is:

1. A trolley head including a trolley wheel and fork, clamp nuts having inwardly extending pivots for cooperation with the trolley wheel and having chambers surrounding the said pivots for containing a lubricant.

2. A trolley head including a trolley wheel and fork, the latter having ofi'standing threaded bushings or tubular extensions, clamp nuts adapted to screw upon said threaded bushings and provided with pivots for cooperation with the trolley wheel.

3. In a trolley head, a trolley wheel having journals depressed in their outer ends, and a fork forming bearings for said journals, clamp nuts having screw thread connection with the fork members and provided with inwardly extending pivots adapted to enter the depressions in the outer ends of the trolley wheel journals.

4. In combination, fork sides comprising shanks, and disk shaped portions centrally perforated and having depressions in their inner faces and having opposite sides of the outer portions of the disk shaped parts beveled in opposite directions, means for connecting the fork members, a trolley wheel having journals obtaining hearings in the open ings of their outer portions and having its ends fitted into depressions of the said disk shaped parts, and a rod connecting said disk shaped portions adjacent their peripheries.

5. In combination, fork sides comprising shanks, and disk shaped portions centrally perforated and having depressions in their inner faces and having opposite sides of the outer portions of the disk shaped parts beveled in opposite directions, means for connecting the fork members, a trolley wheel having journals obtaining bearings in the openings of their outer portions and having its ends fitted into depressions of the said disk shaped parts, and a red one terminal of which is threaded into one of said disk shaped portions adjacent its periphery, the other terminal of said rod extending through the other disk shaped portion adjacent its periphery and receiving a nut.

In testimonv whereof I aflix my signature in presence of two witnesses.
